I've installed NixOS over wifi a few times, most recently for a desktop that wasn't next to my router and that I didn't feel like relocating to connect via ethernet. The fully featured install ISO (not the minimal version) comes with a GNOME desktop environment and you can point-and-click to set up your wifi for the install.
However, a fun trick I learned recently is to tether your phone to your computer while installing any Linux distro. My phone's tether connection over USB just looks like ethernet (as far as I can tell), so there is less fiddling around. My Android phone can tether to my wifi as well, so no need to use your cellular data.
